Chapter 12, Problem 12.10QAP

Interpretation Introduction

(a)

Interpretation:

The goniometer setting in terms of $2\theta$ needs to be calculated for the $\text{L}{\beta }_1$ lines of Br at 8.126 $\stackrel{\text{0}}{\text{A}}$ when the diffracting crustal is ethylenediamine d-tartrate.

Concept introduction:

Bragg’s diffraction condition will be used for the calculation of angle for goniometer setting. This condition is given as-

$n\lambda =2d\sin \theta$

Where,

n = integer

λ= wavelength

d = interplanar distance of crystal

λ= angle
